1. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions
Sammanfattning : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. LÄS MER
2. Aspects of infection and leukemia in Rwanda
Sammanfattning : A first part of this thesis addressed the potential impact of variants of genes encoding interferon-λ4, which is a cytokine that participates in protection against pathogens at epithelial surfaces, for the resolution of upper respiratory tract infections in Rwandan children. In a study of 480 subjects (≤5 years old), where follow-up samples were available from 161 subjects, it was observed that IFNL4 genotypes were associated with clearance of RNA viruses from upper airways.

3. Selected Topics in Homogenization
Sammanfattning : The main focus of the present thesis is on the homogenization of some selected elliptic and parabolic problems. More precisely, we homogenize: non-periodic linear elliptic problems in two dimensions exhibiting a homothetic scaling property; two types of evolution-multiscale linear parabolic problems, one having two spatial and two temporal microscopic scales where the latter ones are given in terms of a two-parameter family, and one having two spatial and three temporal microscopic scales that are fixed power functions; and, finally, evolution-multiscale monotone parabolic problems with one spatial and an arbitrary number of temporal microscopic scales that are not restricted to be given in terms of power functions.

4. Λ/K0s Associated with a Jet in Central Pb–Pb Collisions at √sNN = 2.76 TeV Measured with the ALICE Detector
Sammanfattning : In high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mesons, e.

5. The Symmetric Meixner-Pollaczek polynomials
Sammanfattning : The Symmetric Meixner-Pollaczek polynomials are considered. We denote these polynomials in this thesis by pn(λ)(x) instead of the standard notation pn(λ) (x/2, π/2), where λ > 0. LÄS MER
